The temperature fuse dates back to the late 19th century, when it was invented as an overheating protection device for electrical circuits. The initial temperature fuse, composed of simple materials such as a glass tube and a metal cap, works when when the circuit overheat, the low-melting point metal material inside the fuse breaks, cutting off the circuit and protecting the circuit and equipment. With the continuous progress of science and technology and the continuous expansion of application demand, the types and specifications of temperature fuse are also increasing, and now it has been widely used in various fields and equipment, such as home appliances, automobiles, electricity and so on.
In the process of development, the temperature fuse has gradually formed various types and specifications, such as ordinary type, plug and pull type, box type and so on. At the same time, its use scope is also expanded to different fields and equipment, such as power supply circuit, motor circuit, lighting circuit, etc. In addition, the performance and application of the temperature fuse have also been continuously improved and improved, such as improving the temperature induction sensitivity, reducing the fuse speed, increasing the high temperature resistance, etc.
NEC temperature fuse is a kind of components used for circuit protection, can be in the circuit abnormal, such as the current or temperature is too high, fuse its own wire, so as to prevent circuit overload or short circuit damage to the equipment, temperature induction sensitive, can timely when abnormal circuit temperature, protection circuit is not damaged, cannot be used again after fuse, need to replace a new fuse. It can be used in different circuit application scenarios, such as power supply circuit, motor circuit, etc., with different specifications and rated parameters, which need to be selected according to the specific situation of the circuit.
NEC SF96E Rated voltage 250V. When using NEC temperature fuse, it is necessary to choose the correct fuse rated voltage and current model to ensure that it can withstand the maximum current and voltage of the circuit. When installing the fuse, it needs to follow the instructions in the manual or the circuit diagram to ensure its correct installation and use. Check the status of the fuse regularly and replace it in time. When replacing the fuse, choose the same model, or the same specification and type, to ensure that it works properly and protects it.
